Implementing and Operating Cisco Security Core Technologies (SCOR) — Question 573

An engineer must set up 200 new laptops on a network and wants to prevent the users from moving their laptops around to simplify administration. Which switch port MAC address security setting must be used?

Answer options

• A. aging
• B. static
• C. sticky
• D. maximum

Correct answer: C

Explanation

The correct answer is C, sticky, as it allows the switch to dynamically learn the MAC addresses and retain them even after a reboot, preventing users from changing devices. Option A, aging, pertains to how long learned MAC addresses are retained but does not prevent movement; B, static, requires manual entry of MAC addresses, which can be cumbersome for many devices; and D, maximum, limits the number of MAC addresses, but does not address user mobility.
